Functions and capabilities of current collectors The basic function of a current collector is to connect and deliver the electrons from active electrode materials to the external power supply and vice versa. With a high or low current rate, current collectors should be able to secure that the active materials are well-intact and firmly in contact.
The thermal collector for Al 2 O 3 fluid is located below and attached to the PV solar cell, resulting in the contour being similar to the PV contour in shape and color. In contrast to the basic collector model, the direct flow collector system produces a thermal fluid. The fluid produced in Al 2 O 3 in the cooling system reached 307.97 K.
During the development of SPCs, little attention has been paid to the design of the current collectors (CCs), which draw electric current in/out of the electrochemical device. In conventional (monofunctional) devices, the CCs are continuous metallic foils which also act as supportive substrates upon which the active layer is deposited.
The modeling was carried out in a coupled manner to determine the temperature changes in the PV solar cells and the collector fluid. As such, it was determined that the photovoltaic thermal collector system could improve the performance of photovoltaic solar cells.
A photovoltaic thermal collector system was used by varying the radiation intensity, the shape of the collector design, the type of fluid, and the fluid flow rate to determine the system's electrical efficiency and thermal efficiency.
PCM usage can be increased by 2.1%. The optimization effect of the collector design was studied by increasing the efficiency of PV solar cells by 23.7% [ ]. Technology for converting solar energy through solar collectors to provide heating and cooling.
